SPECIFICATION forming part of Letters Patent No. 469,251, dated February23, 1892.

Application led March l0, 1891. Serial No. 334,433. (No model.)

To all whom t may concern:

Be it known that I, HANS A. IsBERG, of Long Island City, in the countyof Queens and State of New York, have invented a new and ImprovedCopy-Holder, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improvedcopy-.holder designed for the use of type-writers,type-writer operators,

to type-Setters, dac., and which is simple and durable in constructionand arranged for moving the indicating or line bar any desired distanceor equidistant spaces, as desired.

The invention consists of certain parts and details and combinations ofthe same, as will be hereinafter fully described, and then pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

zo in which similar letters of reference indicate corresponding parts inall the figures.

Figure lis a front view of the improvement with parts broken out. Fig. 2is a transverse section of the same on the line n: @c of Fig. 1.

Fig. 3 is an enlarged sectional plan view of the device for carrying theline-bar on the line y y of Fig. l. Fig. '4 is aplan view of the meansfor holding the paper. Fig. 5 is a face view of the space-indicator.Fig. G is an enlarged front view of the gripping and shifting device,and Fig. 7 is a view of the device Jtor locking the base of the frame.

The improved copy-holder is provided with a base A, pivotally connectedat its front end 5 5 at A with the lower end of the frame or table B,adapted to be supported in an inclined position by means of an arm orhanger O, pivoted to the back of the frame B and adapted to engage withits lower end one of a series of teeth or notches A2, formedtransversely in the top of the base A. The latter is provided with legsA3, preferably made of rubber and extending short distances beyond thetop and bottom of the base A, the lower extensions of the said legsbeing adapted to support the base on a table, desk, and the like, Whilethe upper extensions form a rest for the back of the frame A when thelatter is folded onto the base.

On the back of the frame B is arranged a spring-catch O', adapted toengage the rear end of the base A, so as to lock the la'tteronto theframe A in case it is desired to hang the device upon the arm O, thelatter being then extended upward, as is illustrated in Fig. 7. Theframe or table B is preferably made hollow in its front and covered by acover D, on which rests the sheet of paper to be copied and held inplace on the said cover by means of a suitable device E. The latter isprefer- 6o ably formed as illustrated in the drawings and provided witha spring E', adapted to press the upper end of the paper onto the upvper end ofthe cover D. The spring E extends across the upper end of thecover D and is secured in its middle by a rivet E21 or other means to aU -shaped bar E3, passing over one side of the cover D and frame B toextend to the back of the latter, the rear end being fastened to aspring-bar E4, attached to the 7o back of the frame A.

On the left-hand end of the spring E is secured a button E5, projectingthrough a slot in the bar E3 to the front of the same, so as to be takenhold of by the operator when removing the sheet of paper. The right-handend EG of the spring E is curved to the front, so as to permit ofconveniently introducing the sheet of paper to the holder. The sheet ofpaper is passed between the spring E and 8o the cover D, the springsecurely pressing against the front of the paper, so as to hold `thesame in place on the cover D.

On the front of the cover D is arranged to slide up and down the line orindicating bar F, extending across the table from one side to the other,as is plainly illustrated in Fig.

l, the left hand of the said bar being formed with a right-angularextension F', secured in a slide G by means of a setscrew Gi. The 9oslide G is fitted to slide up and down on a hollow guideway B', securedor formed on the left-hand end of the frame B underneath the cover D.The slide G is secured by screws, clamps, or other suitable means to arope or cord ll, made endless, as shown in` Fig. l, and passing over apulley l and under the pulleys I and l2. The pulleys I and Iare mountedto turn on xed studs in the frame A, while the pulley I2 is mounted toturn on roo the plate I3, fitted to slide longitudinally in the lowerright-hand corner yof the trame B ator.

in suitable guideways B2 thereof. rod I4, mounted to turn in the frameB, screws in a projection of the said plate l2, so that by turning thescrew-rod the plate I3 and its pulley I2 can be moved outward to take upany slack which may occur in the rope or cord I-I. In order toconveniently turn the screw-rod I4, a knob or handle I5 is formed on theouter end of the said screw-rod, as is plainly shown in Fig. 1. Thepulley I is located directly above the pulley I', so that that part ofthe rope extending from the pulley I to the pulley I passes through thehollow guideway B' to be engaged by the slide G. By taking hold of theslide G the operator can conveniently move the latter and theindicating-bar F up or down,so as to bring the upper edge of the line orindicating bar below the line to be copied. As soon as the line iscopied the operator moves the slide downward to indicate the next lineof the copy, and so on until the entire inatteron the sheet of the paperis copied.

lVhen the lines on the sheet of paper areplaced equal distances apart,then a device is provided by which the said indicating-bar F is movedthe proper distance whenever the end of a line has been copied by theoper- This device, which does not interfere at any time with theoperator moving the slide G and the indicating-bar F by hand, isarranged as follows: That part of the rope extending between the pulleysI' and I2 is adapted to be clamped against the under edge of a lever J,fulcrumed at J on a plate K, mounted to slide longitudinally in guide-Ways K' fastened on the frame B. The un der side of the rope II isadapted to be engaged by a lever L, fulcrumed at L on the plate K, andprovided with a downwardly-extending nger-piece L2, reaching below theframe B, so as to be within convenient reach of the operator. When theoperator presses on the finger-piece L2 to the right, the lever L swingsupward and presses the rope I-I onto the lever J, the upward movement ofwhich is limited by the lower edge of the guideway K', so that the ropeis clamped between the leversy L and J. By the operator now pulling onthe finger-piece L2 to the right the rope H is carried along, andconsequently the slide G, secured on the side rope, moves downward,thereby moving the indicating or line bar F in the saine direction andthe saine distance. The movement to the right of the plate K is limitedby a stop-pin K2, arranged on the frame B.

On the free end and on the upper side of the lever J is formed a lug J2,adapted t-o engage the under side of the guideway K', and also adaptedto pass into a notch K2, formed in the under edge of the said guideway,at the time the right-hand end of the plate K strikes against thestop-pin K2. As soon as the operator releases the pressure on theiinger-piece L2 the lever L swings downward, so that the rope is setfree, and in order to move A screwthek lever J also downward a link vNis provided. which is fulcrumed on the leverLand extends upward betweentwo lugs J 2, formed on the front of the lever J. The upper end of thelink N is formed with a head N',adapt ed to engage the top of the saidlugs J2 on the downward motion of the link L engages the ysaid lugs J 2,thereby pulling the lever J downe ward to disengage the lug J2 of thesaid lever from the notch K2. A spring O, secured on the frame B andengaging with its free end the plate K, now presses on the latter andforces the saine backward-that is, to the left-into the former position,the rope Il., however, remaining at a standstill, as the said rope isnot clamped between the levers L and J. The movement of the plate K,caused by the spring O, is limited by the said plate K striking againsta bar P, mounted to slide longitudinally in suitable bearings on themain frame B. A screw-rod Q screws in the lug on the said barP and ismounted to turn in the lefthand side of the main frame B, the outer endof the screw-rod being formed with a knob or handle Q' for convenientlyturning the said screw-rod so as to move the bar P inward or outward toregulate the distance the plate K is to slide on its return movement. Onthe bar P is secured a pointer P', which extends to the outside of theframe B, is bent over the cover D, and indicates on a graduated scaleP2, secured to the front of the cover D, as isplainly illustrated inFig. 5. The pointer P' indicates at a glance the distance the line orindicating bar F is moved every time the shifting and tripping device isactuated. In order to enable the operator to conveniently actuate thefinger-piece L2 with one finger, a iixed or stationary finger-piece R isprovided, secured on the lower edge of the frame B next to thelinger-piece L2.

The gripping and shifting device is manipulated as follows: After thesheet of paper or copy has been secured on the front of the cover I) andthe operator has moved the slide G and indicating-bar F to the properplace of starting on the copy then the operator turns the knob Q' so asto shift the bar P until the pointer P indicates on the graduated scaleP2the space between the two successive lines on the sheet of paper orcopy. The spring O by pressing on the plate K forces the latter to theleft, so that the left end of the plate K abuts on the inner end of thebar P. Now when the operator has copied the rst line of the copy anddesires to shift the indicating or line bar F he presses thefinger-piece L2 to IOO IIO

the right, so that the lever L swings upward Y and grips the ropebetween the said lever and the lever J, the upward swinging motion ofthe lever J being limited by the guideway K. The operator by furtherpressing in the same direction on the finger-piece L2 causes the plate Kto slide to the right, so that the gripped rope or cord H moves along,whereby the slide G is carried downward and the line or'guide bar F ismoved in the same direction-that is, below thenext line of the copy. Therear ward motion of the plate K is limited by the stop-pin K2, whichwhen struck permits the lug J2 of the lever J to engage the notch K2, sothat the said plaie K is locked in place in this position. As soon asthe operator re leases the pressure on the tingenpiece L2 the leverswings downward and the rope is disengaged from the two levers L and J.The operator now presses on the finger-piece L2 in the inversedirection-that is, to the left-so that the head N engages the lugs J 3,thereby swinging the lever J downward to disengage the lug J2 from thenotch K2. The spring O now forces the plate K and the several partscarried by it to the left until the plate K abuts` again the bar P. Asthe rope I-I is not gripped at this time, it remains' at a standstill,and consequently the slide G and the indicating or line bar F remain intheir positions. As soon as the operator has copied the line above theline or indicating bar F he again presses the iinger-piece L2 to theright and the abovedescribed operation is repeated. It will be seen thatthe indicating or line bar Fis moved downward equidistant spaces at eachoperation of the gripping and shifting device, the distance the saidline-bar is moved depending on the position of the bar P relative to theplate K. As this distance is indicated by the pointer P' on thegraduation of the scale I2, the operator is enabled to adjust the deviceaccording to the distance between the lines and the copy.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl.
